In this embodiment configured as described above, the control unit 900 may operate to perform the first to third controls as a control operation for controlling the state parameters of the film unit 400 . Hereinafter, each control operation will be described in detail. explained as

The control unit 900 controls the first control for the transparency control of the film unit 400 based on the distance between the present system and a peripheral object (eg, a customer) located in the periphery of the display effector system (hereinafter, the present system) of the present embodiment. This may be performed, and the first control is defined as a control for adjusting the transparency of the film unit 400 to a higher value as the distance between the surrounding object and the present system decreases. A proximity sensor (eg, an infrared sensor or an ultrasonic sensor) may be provided outside the frame unit 100 to obtain a distance from the present system to a nearby object.

As an example of the first control, when a nearby customer is approaching the system, it can be seen that the customer has a will to check the target object accommodated in the internal space of the frame unit 100. , so that the customer can visually check the target object in the internal space of the frame unit 100 to confirm the real object of the target object, as shown in FIG. 5 , the control unit 900 controls each other as the customer approaches the system. As the distance decreases, the transparency of the film unit 400 can be adjusted to a higher value. 900) may be stored in advance. In response to the customer's approach, the transparency of the film unit 400 is increased, so that the view of the target object accommodated in the internal space is gradually secured, so that the customer's interest can be induced according to the visual effect.

Independently from the case in which the transparency of all channels is collectively increased as the customer approaches as in the first control, in the second control, the partial transparent area of the film unit 400 is expanded by expanding the internal space of the frame unit 100 . Although the field of view of the accommodated target object is secured step by step, the light transmission pattern of the film unit 400 is changed step by step to a plurality of preset pattern designs, thereby further improving the visual effect, such as arousing customer curiosity. . The first to third patterns shown in FIG. 6 are examples, and specific patterns may be set to various patterns according to a designer's design. For example, the M-th pattern is maintained in a more transparent state than the M-1 pattern. The number of channels of the film unit 400 may refer to a larger pattern.
